The Masters Brush Cleaner Review: Worth It for Painters?
A small cake of solid soap from General Pencil that painters rub a wet brush on after every session. What it removes, what it does for the bristles and why it is the safest gift when you do not know their medium.
Yes, for any painter who owns brushes they care about. The listing says it removes oils, acrylics, watercolors and varnishes and conditions the bristles in the same step [1]. Skip it only if they already keep a big tub on the sink, since one cake lasts a long time.

Pros and cons
- Dried acrylic that has set hard in a brush will not come back with soap alone
- The small cake is easy to misplace in a cluttered studio
- Not much to unwrap on its own as a gift
Why painters ruin brushes at the sink
Most painters wash brushes with dish soap or hand soap. It gets the color out of the tip, but it strips the hairs and leaves pigment packed near the ferrule, where the bristles splay over time. The Masters cake is made for the job: the listing describes a one step process that cleans and conditions [1].
The routine is simple. Wet the brush, swirl it on the cake, work the lather into the palm and rinse. Repeat until the lather runs white.
Oil, acrylic or watercolor, it does not matter
This is what makes it an easy gift. The listing says it removes oils, acrylics, watercolors, stains and varnishes, and works on glazes and most synthetic finishes [1]. It is rated for sable, bristle and synthetic brushes [1], so you do not need to know their medium or their brushes.
A watercolorist with a pricey sable round and an acrylic painter with a jar of cheap synthetics both get the same use from it.
What soap cannot fix
Acrylic that dried hard in a brush overnight is plastic. Soap softens fresh paint, but it will not rescue a brush left to dry for days, so set expectations if they already have a jar of stiff brushes.
Oil painters still wipe off most paint with a rag and solvent first, then finish with soap. And the cake is small, around the size of a hockey puck cut in half, so it is a stocking stuffer more than a showpiece.
Tucking it into a bigger gift
On its own it is a modest present. It makes more sense as the add-on that rounds out a paint set: tuck it in with the Liquitex BASICS Acrylic Paint Set or the Winsor & Newton Winton oil set from this guide.
For a watercolorist, pair it with the Cotman pocket box. For a holiday stocking, it fits next to a tube of gesso or a small sketch board.
FAQ
Does The Masters Brush Cleaner work on dried acrylic paint?
The Masters Brush Cleaner and Preserver works best on fresh paint at the end of a session. The listing says it removes acrylics, oils, watercolors and varnishes [1], but acrylic that has fully cured in a brush is very hard to remove with any soap. Clean brushes the same day and the cake keeps them soft for years [1]
Is The Masters Brush Cleaner safe for watercolor brushes?
Yes. The listing says The Masters Brush Cleaner and Preserver is for use on sable, bristle and synthetic brushes [1], which covers the soft rounds most watercolorists use. It conditions the hairs while it cleans, so a good sable keeps its point longer than with dish soap [1]
How long does a cake of The Masters Brush Cleaner last?
A long time for most hobby painters. The small cake is used a little at a time, a few swirls per brush, so a weekly painter can go months before it runs low. Heavy studio users buy the larger tub, which is listed separately on Amazon [1]
